Definitions
- the invention relates to a hybrid drive device with an internal combustion engine, an electric machine and a transmission according to the type defined in more detail in the preamble of claim 1.
- Hybrid drive devices are known from DE 102012 009484 B3, FR 2 859 141 A1, DE 102017 112 868 B3, US 2017/0 305258 A1 and DE 102016 013 477 A1.
- DE 102013210013 A1 also describes such a hybrid drive device, in which the electric machine can be connected to the input shaft of the transmission, but to the side of a separating clutch facing away from the internal combustion engine, which is commonly also referred to as a P2 connection with a countershaft serving as an output shaft, which in turn is referred to as a P3 connection.
- the structure has four wheel planes for four individual gears.
- the electrical machine is connected to two idler gears on the input shaft, which in turn form a wheel pair with another idler gear on the countershaft.
- the electric machine can thus alternatively be coupled in the manner described above to the input shaft of the transmission or its countershaft or output shaft.
- the structure is relatively large in relation to the possible number of gears, especially in the axial direction, ie in the direction running along the input shaft of the transmission.
- the object of the present invention is now to specify an improved hybrid drive device which is very compact, especially in the axial direction, and which is also able to shift gears in hybrid mode without a complete interruption in traction.
- this object is achieved by a hybrid drive device having the features in claim 1, and here in particular in the characterizing part of claim 1.
- Advantageous refinements and developments of the hybrid drive device according to the invention result from the dependent claims.
- the hybrid drive device includes an electric machine and a transmission.
- the transmission includes an input shaft and at least two countershafts.
- seven switchable gear pairs are provided, each with a gear wheel arranged coaxially to the input shaft.
- a pair of wheels within the meaning of the invention is to be understood as meaning two meshing gears, one of the two being arranged coaxially with the input shaft and the other of the two being arranged coaxially with one of the countershafts.
- the two gears of the gear pair are arranged in a gear plane that is perpendicular to the axis of rotation of the input shaft.
- a first of the wheel pairs comprises two loose wheels, one on the input shaft and one on the first countershaft.
- the electrical machine is connected to this first pair of wheels in such a way that torques can be introduced into the transmission from the electrical machine via the first pair of wheels. Due to the configuration of the first pair of wheels via two loose wheels, both a P2 connection and a P3 connection are possible.
- the first shiftable wheel pair, a first shifting element level, the second shiftable wheel pair, the third shiftable wheel pair, the fifth shiftable wheel pair, a second shifting element level, the sixth shiftable Wheel pair, the seventh switchable wheel pair are arranged one after the other in the order mentioned, with the third and the fourth switchable wheel pair being arranged in the same axial wheel plane.
- the switching element at least one sliding sleeve and a claw toothing and in an advantageous embodiment further comprises a synchronizing device.
- a shifting element plane is a plane that is arranged perpendicularly to the axis of rotation of the input shaft and intersects at least two shifting elements, the at least two shifting elements being arranged coaxially to different shafts, the shafts being understood to mean the input shaft, the first countershaft and the second countershaft .
- a circuit element plane “comprising” a circuit element it is meant that this circuit element plane intersects at least a part of that circuit element.
- a driven gear plane is a plane which is arranged perpendicularly to the axis of rotation of the input shaft and which includes the driven gears which are arranged in a rotationally fixed manner on the countershafts.
- Connected in a rotationally fixed manner in the context of the invention means that the elements connected in this way are arranged coaxially to one another and rotate at the same angular velocity or rotational speed.
- the hybrid drive device according to the invention with seven gears uses a clever arrangement of the wheel planes and the switching element planes together with a double wheel plane for a very compact structure, especially in the axial direction.
- a double wheel plane refers to a plane that is perpendicular to the axial direction and in which two wheel pairs are arranged that share a gear wheel. Due to the special wheelset architecture, a construction of the transmission in the hybrid drive device according to the invention is possible at very low cost. In addition, despite the simple structure, the full functionality and a high level of comfort in the circuits are given, in particular, switching can be done without an interruption in traction.
- the first pair of wheels is arranged along the input shaft in the last wheel plane as seen from the separating clutch, with the electrical machine overlapping the separating clutch in the axial direction.
- the axial direction means the direction of the axis of rotation of the input shaft.
- the overlapping arrangement within the meaning of the invention means that the elements mentioned can lie in the same axial plane or preferably protrude in the axial direction into the same axial plane.
- An axial plane means a plane that is perpendicular to the axis of rotation of the input shaft.
- the hybrid drive device can preferably do without a separating clutch capable of starting off and, in particular, also without a mechanical reverse gear.
- the diameter of the separating clutch can be designed to be correspondingly small, so that it can be arranged overlapping the electric machine to save space and, according to an extremely favorable development, also overlapping the two driven wheels on the two countershafts.
- a hybrid vehicle with the hybrid drive device according to the invention it is then possible for this to be used together with another purely electrically driven axle to drive an axle driven via the hybrid drive device.
- Starting processes and reversing can then be implemented purely electrically with one or both electrical machines, ie that of the hybrid drive device according to the invention and that of the further purely electrically driven axle.
- the shifts within the transmission can take place without load interruption, in that the electric machine in the P3 connection compensates for or supports the speeds and torques accordingly during the shift.
- the special wheel set architecture of the hybrid drive device can also provide that the first wheel pair comprises a first gear wheel arranged coaxially to the input shaft and a second gear wheel arranged coaxially to the first countershaft, the third wheel pair comprises a fifth gear wheel arranged coaxially to the input shaft and a sixth gear wheel arranged coaxially to the second countershaft and the fourth gear pair comprises a seventh gear wheel arranged coaxially to the input shaft and an eighth gear wheel arranged coaxially to the first countershaft.
- the first shifting element level comprises at least one third shifting element arranged coaxially to the first countershaft and a first shifting element arranged coaxially to the input shaft
- the second shifting element level comprises at least one sixth shifting element arranged coaxially to the second countershaft and one seventh shifting element arranged coaxially to the first countershaft.
- the first shifting element is provided for the non-rotatable connection of the first gear to the input shaft
- the third shifting element is provided for the non-rotatable connection of the second gear to the first countershaft
- the fourth shifting element for non-rotatable connection of the seventh gear is provided with the first countershaft
- the fifth switching element is provided for non-rotatable connection of the sixth gear with the second countershaft.
- the fourth shifting element and the third shifting element and/or the first shifting element and the second shifting element can each be designed as shifting elements with a common sliding sleeve. This makes the transmission even cheaper in terms of actuators and even more compact in design.
- a very favorable embodiment of the hybrid drive device according to the invention can also provide that the seventh wheel pair forms an associated pure wheel plane.
- a pure gear plane is to be understood as meaning a plane which is perpendicular to the axis of rotation of the input shaft and which only intersects a pair of gears but not a shifting element. This also contributes to the compact design.
- a very advantageous development of the hybrid drive device according to the invention can also provide that the fifth and the sixth wheel plane each have a fixed wheel include coaxial to the input shaft.
- the idler wheel of the corresponding wheel pairs in these wheel planes, which then serves as the driven wheel, is then seated coaxially with one of the countershafts and the other idler wheel is coaxial with the other of the countershafts.
- Which one sits on the first and second countershaft is essentially irrelevant, since in both cases the free installation space on the other of the countershafts in the fifth wheel plane can then be used by a shifting element to support the compact axial structure.
- a further advantageous variant of the hybrid drive device according to the invention can also provide for a gear wheel of the third gear plane, i.e. the double gear plane, and a gear wheel of the second gear plane or the fourth gear plane to be arranged coaxially with one of the countershafts, namely directly adjacent to one another.
- Directly adjacent is to be understood as meaning an arrangement in which no switching element and no other gearwheel is arranged on the same shaft between the two directly adjacent elements.
- the arrangement according to this embodiment allows the installation space for switching elements on the countershaft to be used alternately in such a way that they can be positioned in a very space-saving manner in relation to other adjacent switching elements or gears, in particular with a common sliding sleeve.
- a further shifting element plane to be formed in the axial direction between the first shifting element plane and the second wheel plane.
- This additional shifting element level which could also be referred to as the third shifting element level, includes the second shifting element and the fourth shifting element, with the fourth shifting element being arranged coaxially with one of the countershafts and the second shifting element being arranged coaxially with the input shaft.
- 1 shows a first possible variant of the hybrid drive device according to the invention
- 2 shows a second possible variant of the hybrid drive device according to the invention
- the wheel set plans which are used to show the 7-speed gearbox installed in them, are not to be understood to be to scale, nor are all the components necessarily in the plane of the page in which they are shown.
- the dimensions of the components shown in relation to each other do not have to correspond to the real structure.
- FIG. 1 shows a first variant of the hybrid drive device 101, which includes an internal combustion engine 2 on the one hand and an electric machine 3 on the other.
- Internal combustion engine 2 is directly connected to an input shaft 5 of a transmission of hybrid drive device 1 via a separating clutch 4 .
- the direct connection can optionally include a device 6 for absorbing and/or damping torsional vibrations, for example a dual-mass flywheel, between a crankshaft of the internal combustion engine 2 and the separating clutch 4, so that "direct” is to be understood here in such a way that no further transmission elements such as clutches, translations or the like between the crankshaft of the internal combustion engine 2 and the separating clutch 4 are arranged.
- five gears designed as fixed gears namely a third gear Z3, a fifth gear Z5, an eighth gear Z8, a tenth gear Z10 and a twelfth gear Z12, are arranged on the input shaft 5, as well as in the Separating clutch 4 viewed in the axial direction a on the last arranged wheel plane, here the first wheel plane RE1, a first gear Z1 with an associated first switching element S1.
- Two countershafts namely a first countershaft V1 and a second countershaft V2, are arranged parallel to the input shaft 5 in each case.
- Both countershafts V1, V2 have driven gears 7, 8 in a driven gear plane AE, which in turn mesh with a differential gear, not shown here, namely an input gear of a differential gear, directly or via at least one intermediate gear element.
- a first output gear 7 of the output gears 7, 8 is connected in a torque-proof manner to the first countershaft V1
- a second output gear 8 of the output gears 7, 8 is connected in a torque-proof manner to the second countershaft V2.
- the first wheel pair RP1 is the last wheel pair RP1 viewed in the axial direction a from the separating clutch 4 and is therefore arranged in the last wheel plane RE1 viewed in this direction. It includes the first gear Z1, which is designed as a loose wheel on the input shaft 5, and a second gear Z2, which is also designed as a loose wheel and is arranged coaxially with the first countershaft V1. As already mentioned, the first gear wheel Z1 can be connected in a torque-proof manner to the input shaft 5 via the first shifting element S1, the second gear wheel Z2 can be connected in a torque-proof manner to the first countershaft V1 via a third shifting element S3, if required.
- the electric machine 3 is then connected via a pinion 9, which is connected in a torque-proof manner to a rotor shaft 10 of the electric machine 3, on the first pair of wheels RP1.
- the pinion 9 can also mesh with the first gear wheel Z1.
- An intermediate wheel or an intermediate shaft is advantageously arranged between the pinion 9 and the respective gear wheel Z2, Z1.
- Torque can thus be introduced from the electric machine 3 into the transmission.
- a so-called P2 connection can be implemented, in which the electric machine 3 via the pinion 9 and the second gear wheel Z2 of the first wheel pair RP1, which rotates loosely on the first countershaft V1, and that connected to the input shaft 5
- the first gear wheel Z1 coupled via the first switching element S1 acts on the input shaft 5, specifically on the side of the separating clutch 4 facing away from the internal combustion engine 2.
- Shift position within the transmission then takes place via the first countershaft V1 and its first output gear 7 or the second countershaft V2 and its second output gear 8.
- the body is switched to a so-called P3 connection, in which, with the first shifting element S1 open and correspondingly rotating on the input shaft 5, the first gear Z1 rotates and the second gear Z2 of the first gear pair PR1 is coupled to the first countershaft V1 via the third shifting element S3 first countershaft V1 and thus its first output gear 7 is driven directly.
- the internal combustion engine 2 can be started by means of the electric machine 3, or the internal combustion engine 2 drives the electric machine 3 as a generator.
- the electric machine 3 is arranged so that it overlaps the separating clutch 4 in the axial direction a.
- This enables an extraordinarily compact structure in which the electric machine 3 is connected to the last wheel plane, namely to the first wheel plane RE1, seen in the axial direction a from the separating clutch 4 and its simultaneous axial overlapping of the separating clutch 4, i.e. protruding guarantees an extremely compact structure in the plane of the separating clutch 4 which is perpendicular to the axial direction a.
- the separating clutch 4 could also be designed to overlap with the driven gears 7, 8 in the axial direction a, so it would protrude into the driven gear plane AE.
- the separating clutch 4 is designed as a separating clutch 4 that cannot be started, since its diameter can then be selected to be sufficiently small for such an arrangement. Due to the hybridization of the hybrid drive device 101 and the variants 102, 103 and 104 described below, this is unproblematic since the starting process can be easily implemented via the electric machine 3 even if the separating clutch 4 is not capable of starting.
- the first wheel pair RP1 follows the second wheel pair RP2 with the third gear wheel Z3, which is designed as a fixed wheel on the input shaft 5.
- a fourth gear Z4 on the second countershaft V2 forms the other gear of the second wheel pair RP2, ie its output gear.
- This fourth gear wheel Z4, designed as a loose wheel, can be coupled to the second countershaft V2 via a second shifting element S201, if required.
- the third gear plane RE3 then follows in the axial direction after the second gear plane RE2. It comprises a fifth gear wheel Z5 which is designed coaxially on the input shaft 5 as a fixed wheel. This meshes in the third wheel pair RP3 with a sixth gear Z6 as a loose wheel on the second countershaft V2, switchable with a fifth switching element S501.
- this third gear plane RE3, which is designed as a dual gear plane there is also the fourth gear pair RP4, which is a combination of the fifth gear wheel Z5 designed as a fixed wheel and a seventh gear wheel Z7 designed as a loose wheel on the first countershaft V1.
- a fourth shifting element S401 which can be shifted with the third shifting element S3 via a common sliding sleeve, can be used to connect this seventh gear wheel Z7 in a rotationally fixed manner to the first countershaft V1, if required.
- This third gear plane RE3, designed as a double gear plane is followed by a fourth gear plane RE4, which is designed with an eighth gear wheel Z8 as a fixed wheel on the input shaft 5 and a ninth gear wheel Z9 designed as a loose wheel on the first countershaft V1.
- the associated seventh switching element S701 can, if required, connect the ninth gearwheel 9 to the first countershaft V1 in a torque-proof manner.
- the two gears Z8 and Z9 form the fifth gear pair RP5.
- the sixth gear pair RP6 is then formed on the axially adjacent fifth gear plane RE5. It includes a tenth gear Z10, which is designed as a fixed gear on the input shaft 5, and an eleventh gear Z11, which is designed as a loose wheel on the second countershaft V2.
- a first shifting element S6 assigned to it can be actuated together with the fifth shifting element S501 in turn with a jointly used sliding sleeve.
- the first wheel plane RE1 and the sixth wheel plane RE 6 form so-called pure wheel planes in this structure of the drive device 101 . There is no switching element in this gear plane, only gears.
- the twelfth Gear Z12 is designed as a fixed wheel on the input shaft 5, the thirteenth gear Z13 as a loose wheel on the first countershaft V1. If required, it can be connected in a torque-proof manner to this countershaft V1 via an eighth shifting element S8.
- This sixth gear plane RE6 is then followed by the above-mentioned driven gear plane AE, in which at least the two driven gears 7, 8 of the countershafts V1, V2 are located, and in which in particular—but this is not shown here—the separating clutch 4 is also arranged can be.
- the electrical machine 3 overlaps this output gear plane AE and the separating clutch 4 in the axial direction a.
- a second shifting element level SE2 lies between the fourth gear plane RE4 and the fifth gear plane RE5 and includes the seventh shifting element S701 and the sixth shifting element S6, while the fourth shifting element S401 is in the second gear plane RE2 and the fifth shifting element S501 in the fourth gear plane RE4 and the eighth Switching element S8 are arranged in the fifth gear plane RE5.
- the transmission of the hybrid drive device 1 can be designed in such a way that it is used as a seven-speed transmission without a mechanical reverse gear. In particular, reversing takes place via the electric machine 3. This can also be used for starting, in order to manage with a correspondingly small separating clutch 4, which in this case does not have to be capable of starting, as already mentioned.
- the first wheel plane RE1, the fourth wheel plane RE4 and the sixth wheel plane RE6 have their respective wheel pair RP1, RP5 and RP7 from the input shaft 5 to the first countershaft V1, the second wheel pair RP2 in the second wheel plane RE2 and the sixth wheel pair RP6 in the fifth Wheel plane RE5 to the other countershaft V2.
- the dual gear plane in the third gear plane RE3 transfers the sixth and seventh gear to the two countershafts V1, V2, for example.
- the translations can be designed in such a way that the first gear is realized via the sixth gear pair RP6 in the fifth gear plane RE5, the second gear via the fifth gear pair RP5 in the fourth gear plane RE4, the third gear via the first gear pair RP1 in the first gear plane RE1 and the fourth or fifth gear alternately via the second gear pair RP2 in the second gear plane RE2 or via the seventh gear pair RP7 in the sixth Wheel plane RE6.
- the sixth and the seventh gear could then be implemented via the double gear plane RE3, for example the sixth gear via the third pair of wheels RP3 and the seventh gear via the fourth pair of wheels RP4.
- a specific exemplary embodiment of this could provide, for example, first gear via the sixth pair of wheels RP6 in the fifth gear plane RE5, second gear via the fifth pair of wheels RP5 in the fourth gear plane RE4, third gear via the seventh pair of wheels RP7 in the gear plane RE6 , fourth gear via the first wheel pair RP1 in the first gear plane RE1, fifth gear via the second wheel pair RP2 in the second gear plane RE2 and sixth gear and seventh gear via the wheel pairs RP3 and RP4 of the dual gear plane RE3, for example the sixth Gear on the third pair of wheels RP3 and the seventh gear on the fourth pair of wheels RP4.
- the first shifting element S1 and the second shifting element S202 in this variant can now, like the third shifting element S3 and the fourth shifting element S401, which was also the case before, be designed as a kind of double shifting element with a common sliding sleeve. This saves effort in terms of control and actuators.
- a further shifting element level SE3 is created, which is interposed between the first shifting element level SE1 and the second gear level RE2 in the order described above.
- the further structure of the hybrid drive device 102 is analogous to the already described structure of the hybrid drive device 101 in the preceding figure.
- the use of the individual wheel pairs RP1 to RP7 and the corresponding wheel planes RE1 to RE6 for the corresponding gear ratios can in turn be implemented analogously to the variant of the hybrid drive device 101 in FIG. 1 in this variant of the hybrid drive device 102.
- the double wheel plane RE3 with its two wheel pairs RP3 and RP4 can be used for the sixth and seventh gear.
- the other wheel planes RE1 to RE6 and wheel pairs RP1 to RP7 are again possible analogously to the embodiment variant 101 from FIG. 1 already described above.
- both of the above-described possibilities of the gear ratios can be used in an analogous manner, just like the specific exemplary embodiment.
- the second pair of wheels RP2 no longer drives toward the second countershaft V2, but instead toward the first countershaft V1. Then follows the double wheel level RE3 with the wheel pairs RP3 and RP4, as before. The structure is then reversed in the fourth gear plane RE4. Instead of driving the fifth wheel pair RP5 to the first countershaft V1, the output here changes to the second countershaft V2. The same also applies to the two other wheel pairs RP6 and RP7, which also drive the respective other countershaft V1, V2 than in the previous variants of the hybrid drive device 101, 102.
- the previous fourth shifting element moves accordingly in the axial direction of the first countershaft V1 to the other side of the double gear plane and is here now with S402 designated.
- the seventh switching element moves from the first to the second countershaft and is now labeled S702 accordingly.
- the switching elements S6 and S8 remain largely in their place, but are shifted in the axial direction along the countershafts as a result of the new design.
- a further aspect relates to the fifth shifting element S501 for the non-rotatable connection of the sixth gear wheel Z6, designed as a loose wheel, of the third wheel pair RP3 to the second countershaft V2. This migrates to the other side of the gear wheel Z6 in the axial direction and, in the exemplary embodiment shown here, is displaced axially into the first shifting element level SE1.
- This variant of the hybrid drive device 103 now allows dual use of the dual gear plane RE3 with the wheel pairs RP3 and RP4 for the fifth and sixth gear.
- the structure can have translations such that the fifth wheel pair RP5 in the fourth wheel plane RE4 and alternately the sixth wheel pair RP6 in the fifth wheel plane RE5 provide gears one and two.
- the third gear can again be realized via the first pair of wheels RP1.
- the fourth gear and the seventh gear can be implemented alternately either via the second pair of wheels RP2 or the seventh pair of wheels RP7, while the fifth gear and the sixth gear are implemented via the two pairs of wheels RP3 and RP4 of the double gear plane RE3.
- hybrid drive device 104 differs from the previously described variant of hybrid drive device 103 only in that the fifth shifting element, referred to as S502 in variant 103, which was arranged there in the first shifting element level SE1, is now referred to as fifth shifting element 503 and is arranged axially displaced in the second wheel plane RE2 on the second countershaft V2. Otherwise, the structure corresponds to that of the previously described variant.
- the gears in this variant of the hybrid drive device 104 could now be realized, for example, in such a way that the sixth wheel pair RP6 in the wheel plane RE5 and the fifth wheel pair RP5 in the fourth wheel plane RE4 alternately take the first or form second gear, while the second pair of wheels RP2 in the second gear plane RE2 and the seventh pair of wheels RP7 in the sixth gear plane RE6 alternately form gears three and seven.
- the fourth gear could then be implemented via the first wheel pair RP1 in the first gear plane RE1, while the two wheel pairs RP3 and RP4 in the wheel plane RE3 used as a double wheel plane could form the fifth and sixth gear.
- the hybrid drive device 101, 102, 103, 104 can preferably be used to drive a first driven axle of a vehicle in which a second driven axle is driven purely electrically. In principle, the vehicle could then have additional driven or non-driven axles, with the structure as a passenger car typically providing two axles.
- Such a hybrid car is the preferred, but not the exclusive, purpose of use for the hybrid drive device 101, 102, 103, 104.
